How to Look After 4D Number Plates

4D number plates are one of the most popular car styling upgrades thanks to their bold, raised characters and sleek, modern design. But to keep them looking sharp, it’s important to know how to look after 4D plates properly. In this guide, we’ll cover cleaning techniques, protection tips, legal considerations, and maintenance advice to ensure your plates stay in top condition for years.

What Are 4D Number Plates?

4D plates feature laser-cut acrylic characters that are bonded to the surface of a standard reflective plate. This gives them a sharper, more defined look than traditional 2D or 3D plates. Because of their layered design, they require a little more care to keep the raised characters clean and secure.

Why Proper Care Matters

Looking after your 4D plates isn’t just about appearance—it’s also a legal requirement. Plates that are dirty, cracked, or illegible can result in fines and MOT failures. Regular maintenance also helps protect your investment and extend the lifespan of your plates.

How to Clean 4D Plates

Here’s a simple cleaning routine to keep your plates looking fresh:

  • Rinse first: Use warm water to wash away loose dirt and grit before wiping.
  • Use mild products: Mix car shampoo or mild soap with water—avoid harsh chemicals.
  • Soft cleaning tools: A microfiber cloth is ideal. For stubborn grime, use a soft-bristle brush gently.
  • Rinse thoroughly: Remove all soap residue with clean water.
  • Dry completely: Use a dry microfiber towel to prevent streaks or water spots.

Protecting Your 4D Plates

  • Avoid pressure washer damage: Keep the nozzle at a safe distance to avoid dislodging raised characters.
  • No harsh chemicals: Bleach or abrasive cleaners can damage the acrylic surface.
  • Use covers: A clear protective plate cover can help shield plates from dirt and stone chips.
  • Regular checks: Inspect your plates for loose letters, scratches, or cracks.

Legal Considerations

Even when properly cared for, your 4D plates must remain DVLA compliant. To stay road legal, ensure that:

  • Characters are clearly visible and not obscured by dirt or damage.
  • The font, size, and spacing match DVLA rules (Charles Wright font).
  • Your plates display the supplier’s name, postcode, and BS AU 145e mark.

Dealing with Common Damage

  • Scratches: Light scratches can often be reduced using a plastic-safe polish.
  • Loose characters: If a letter becomes loose, reattach it using an acrylic-safe adhesive.
  • Severe cracks: Plates with major damage should be replaced to remain road legal.

Storage Tips

  • Clean first: Always wash and dry plates before storing.
  • Wrap individually: Use soft cloths or bubble wrap to prevent surface damage.
  • Store flat: Keep plates flat in a dry, shaded area to avoid warping.

How to Extend the Life of Your 4D Plates

  • Regular cleaning: Especially after driving in poor weather or on dirty roads.
  • Gentle handling: Avoid scrubbing or knocking the raised acrylic characters.
  • Limit sun exposure: Parking in shaded areas can help reduce UV-related wear.
  • Seek advice: If you notice ongoing wear or adhesive issues, professional advice can help.

Conclusion

Knowing how to look after 4D plates will keep them stylish, road-legal, and durable. With regular cleaning, gentle handling, and proper protection, PrimoPlates 4D number plates will continue to look sharp and remain compliant for years to come.
